UFC 4-150-02

Regardless of the variations in utility groups that may be necessary to
accommodate deck fittings and pier construction, sewer and oily waste connections
must always be located 3.05 m (10 feet) or more from domestic water connections.
Electrical outlet assemblies must be separated from other utility outlets by at least 10
feet (3.05 m) whenever possible. Additionally, where fueling is required, separation
between such connections and electrical equipment is mandatory. See MIL-HDBK-
1022A, Petroleum Fuel Facilities and consult with the cognizant Fire Protection
Engineer to ascertain the minimum separation distances. Separation distances will vary
depending upon the type of fuel or fuels.

Hose and Cable Lengths. Experience has shown that if utilities are to be
grouped, not all of the shore connections can be placed optimally in regard to their
respective ship connections, even at a dedicated berth. This being the case, the
location of connections for certain utilities should be given preference in order to
minimize required hose lengths. Preference should be given, in order of importance, to
electrical power, fire protection water (if required), steam, sewage, oily waste collection,
and potable water. Excessive hose and cable lengths have significant disadvantages
as defined below.
2-2.2.1
Electrical Power. Excessive lengths of power cable increase the
possibilities of accident, fire, and excessive voltage drop.
2-2.2.2
Fire Protection Water. Losses in the fire protection system hoses could
be critical in the event of fire, particularly when ship's pumps are under repair.
2-2.2.3
Steam. Steam hoses have a very short life, are expensive, and usually
have high-pressure losses from shore to ship.
2-2.2.4
Sewage. Although added hose pressure loss is not normally a problem,
sewage hose is heavy, difficult to support, and must be disinfected when the ship's
connection is broken.
2-2.3
Group Locations and Spacing. The locating dimensions for shipboard
utility connections of various ship classes are presented in SCDB. These dimensions,
when used with the ships configuration drawings and the parameters given in this UFC,
provide guidance in spacing determinations for the shore connections. The locations of
required deck equipment (capstans, bollards, cleats, ladders, and railings) and deck
operations (brows, cranes, dumpsters, etc.) must always be coordinated with locations
of utility connections. Pier berthing plans (graphic plots) must be made for the most
likely ship mixes, and should consider local berthing practices as defined by the Activity.
The berthing plans provide the basis for the design and operations of the pier's utility
systems and must be included in the construction contract drawings when included
under the design contract. Suitable shore connection spacing for the range of possible
ships must be provided. Individual utilities within groups for mixed berthing should
generally not be more than 66 m (200 ft) apart. Whenever possible, shore utility
connection spacing should be such that connections are not offset more than 15.24 m
